Ladies and gentlemen, it's always a pleasure to welcome

to welcome Professor Amos Johnson back to Cambridge because we think he's actually one of ours.

The fact that he has been teaching in the other place

for now quite some time is now that you know there.

Angus is professor of law and fellow in law at University College and has a BA, DCL from Oxford,

unfortunately, and L.M from the University of Leiden. He's author of many books and teaches EU law and tort law and is one of the experts on EU environmental and

energy law. Today he is going to talk to us about renewable energy certificates.

And it's going to share some of this research that has been going on for quite some time.

We're going to have about 40 minutes of lecture and then there will be ample space for questions and comments.

Thank you, guys. Thank you.

Well, it's great to have been invited back. Thank you very much. And it's also nice to come back to somewhere that I feel I owe a

great debt to, so I'm able publicly to acknowledge that this place was very, very kind to me and

great to me, and still talks to me even though I had the temerity to leave and go somewhere else.

So thank you very much. I find myself in a bit of a quandary talking about this kind of topic,

because I never really thought I was an environmental lawyer, but it turns out that being an energy lawyer made me one when suddenly everyone decided that the way to achieve a variety of environmental, important environmental goals was through the energy sector and various aspects of it.

And that particularly, I think, become very clear in the fields of

emissions trading, emissions control, and also in the field of trying to promote renewable energy.

This is, for some countries, obvious, and for other countries, a very controversial idea,

simply because there's a variety of different natural resources that different countries

actually have in the field of renewable energy. On a day like today, you can think that the

British pursuing solar energy might be a bit of a challenging thing to do, for example, although

technology is improving and maybe it makes sense in a lot of ways here too. But this topic all stems from a question I was once asked by a bunch of Cambridge economists.
